i left the vertical wires in place and connected an input jack to the horizontal wires. This gave me vertical waveforms when i ran audio into it.
so i rotated the coils 90 degrees to get horizontal waveforms.

the advantage of this is, that i can use the Vhold and Vsize trimpots to adjust the display to the respective waveform and somewhat "lock" the waveform to the sceen.

this is how it looks when i hook it up to one of the speaker outs of my home stereo:

however, i would like to make this thingy standalone by adding a built-in amplifier. Because now, i can't turn up the volume on my stereo without altering the amplitude on the screen.

i had this module laying around, but the waves on the screen lose their smooth sexyness when i use it via my stereo's rec out.

pls compare the 2 attached pics

so my question is, what are my options? get anothe hifi amp and use it solely for the TV?
or are there any good low-distortion, low cost, low effort amp kits/modules/plans out there that are recommended for sth like this?

the coil reads around 1,7 ohms btw, not sure how long my stereo wants to deal with that..

I suggest going to a pawn shop, or 2nd hand shop, and pick up an old ugly relic stereo amp that nobody wants. Most solid-state amps should be able to kick 1.7 ohms. I would be careful driving your new display TV with a good home hifi.

so i finally found an old schneider 6145ea "HIFI" amp at the flea market for 8 bucks. Sounds crappy, but works fine for the tv on the rec out of my regular amp and has 3 more switchable inputs (2 of which are working ).

don't care too much if this thing will be fried, so i ditched the transformer idea and hooked the tv straight to a speaker out.

I connected the wires from the horizontal deflector coil to the vertical supply
Then I connected the wires from the vertical deflector coil to a small amplifier.
The output is very small. It is a horizontal line.
I'm not quite satisfied. But it still looks nice.

Servus! The initial post by daniel mentioned, that it is possible to get a colour adjustable circuit bent tv running. unfortunately the links he provided in the beginning of the topic do not work anymore and I can't seem to find a hint on how to do that elsewhere. does someone know, where to find this information, as I am ok with most of the fiddling around but I cannot seem to figure it out by myself. he mentioned censtron doing that in 2006... yours, brother jacob
